I would also like to point out

Bellamy was a minister at the time he wrote the Pledge, yet he did not include any words about God. Why? Because nations and governments are human constructions, not godly creations, and it was important to him to keep God and politics separate.

He died before "under God" was inserted into the Pledge in the 1950's, but his daughter fought to prevent the Pledge from becoming a semi-religious creed.
